Ecole Centrale de Nantes, Fluid Mechanics Laboratory (ECN), France
Main topics:
- Thermal convection induced by the differential heating of the wall and street surfaces.
- Air motion and the turbulence induced by the vehicles themselves.
- Geometrical structure of the surrounding quarter in non-simple geometries.
- Exchanges of momentum, heat, and various components of the urban pollution at the canopy-atmosphere interface at roof level.
Current Research:
CFD modelling of turbulent flows and pollutant dispersion at street-to-urban scales:
- Pollutant transport and dispersion within urban canopy.
- Canopy-Atmosphere dynamics and thermodynamics exchanges.
- Parameterization of urban grounds as a patchyness of roughness and heat/humidity fluxes.
- Street canyons: CFD studies and validation versus atmospheric wind-tunnel physical models (street scale validation experiments in progress).

Proposed work within TRAPOS project:
Quantifying the influence on flows, pollutant mixing and dispersion within streets of the four following factors:
- the thermal convection induced by the differential heating of the wall and street surfaces due to (solar) radiation exchanges and heat storages,
- the air motion and the turbulence induced by the vehicles themselves,
- the geometrical structure of the surrounding quarter in non-simple geometries and the presence of horizontal fluxes of pollutants at ground level,
- the exchanges of momentum, heat and various components of the urban pollution at the canopy-atmosphere interface at roof level.
